Your breasts go through an amazing transformation
when you are pregnant.
They go from being primarily fatty tissue to milk making machines. In fact, the lactating breast has about twice as much milk making tissue as fatty tissue. These changes are usually complete by week 22 of your pregnancy. 12 weeks before you deliver, your breasts grow, get heavy, and start making colostrum.
Colostrum is produced in tiny amounts (20 to 40 ml per day) in the first few days after your baby is born. It is very rich in nutrients, which makes it ideal for your baby’s developing digestive system.
